1-1. Introduction
The Fluke Model 5700A/5720A Series II Calibrators are precise instruments that
calibrate a wide variety of electrical measuring instruments. These calibrators maintain
high accuracy over a wide ambient temperature range, allowing them to test instruments
in any environment, eliminating the restrictions to calibrate only in a temperature-
controlled standards laboratory. With a 5700A/5720A Series II, you can calibrate
precision multimeters that measure ac or dc voltage, ac or dc current, and resistance. The
5720A Series II operates in a similar manner to the 5700A Series II, the difference is that
the 5720A Series II has a considerably higher specified accuracy. Option 5700A-03
Wideband AC Voltage, which is available for both the 5700A Series II and the 5720A
Series II, extends this workload to include rf voltmeters.
Specifications are provided at the end of this chapter. The calibrator is a fully-
programmable precision source of the following:
• DC voltage to 1100 V
• AC voltage to 1100 V, with output available from 10 Hz to 1.2 MHz
• AC and DC current to 2.2 A, with output available from 10 Hz to 10 kHz
• Resistance in values of 1x10
n
and 1.9x10
n
from 1 Ω to 100 MΩ, plus a short
• Optional wideband ac voltage from 300 µV to 3.5 V into 50 Ω (-57 dBm to
+24 dBm), 10 Hz to 30 MHz
Features of the calibrator include the following:
• Internal environmentally-controlled references allowing the calibrator to maintain
full performance over a wide ambient temperature range
• Automatic meter error calculation obtained through using a simple output adjust
knob; the display shows linearity, offset, and scale errors
• Keys that multiply and divide the output value by 10 to simplify work on meters with
calibration points at decade multiples of a fraction of full-scale
• Programmable entry limits used for restricting the levels that can be keyed into the
calibrator, preventing access to levels that may be harmful to equipment or personnel
• A s key that provides the capability of displaying the instrument’s specification at
the selected operating point, calibration interval, and specification confidence level
• An auxiliary current binding post that allows you to calibrate meters with separate
current inputs without moving cables
• Real-time clock and calendar for date stamping reports
• Offset and scaling modes that simplify linearity testing of multimeters
• Variable phase reference signal output and phase-lock input
• Interface for the Fluke 5725A Amplifier
• Standard IEEE-488 (GPIB) interface, complying with ANSI/IEEE Standards 488.1-
1987 and 488.2-1987
• Selectable normal remote mode or emulation of the Fluke 5100B and 5200A Series
calibrators in functions and response to system controller software
• EIA Standard RS-232C serial data interface for printing, displaying, or transferring
internally-stored calibration constants, and for remote control of the calibrator
• Extensive internal self-testing and diagnostics of analog and digital functions
